    Abstract
  • To reduce the dynamic stress of rotor blades under the wake of front stator vane,an asymmetry stator mistuned design was conducted.According to mistuned blade design for the asymmetry stator,the wake force on rotor changed from single frequency and higher amplitude to multi-frequency and lower amplitude.The frequency and amplitude of wake force were deduced theoretically,while the influence of stator sector distribution and stator vane quantity on the wake force of vane was also discussed.Transient analysis was conducted for the forcing response of rotor blades under the same stator sector distribution and different quantities of stator vane,so an optimum asymmetry stator mistuned design was developed.
